Planes, trains and tablets
I've never owned a tablet, having never had the desire to spend hundreds of pounds on one. I've never felt I've missed out, but am always slightly envious of tablet owners on planes and trains, when in one smooth motion they whip out their slablets, flip over the cover and continue watching some fun hi-def movie or tv show.
Often, I'll do the same but less smoothly with my (relatively-small-but-still-larger-than-a-tablet) 13" laptop, which struggles to even fit on the tiny tables present on trains or planes. When watching something awkwardly on a plane and we're about to take-off or land, a steward or stewardess is guaranteed to come over and tell me to put it away. Tablet owners on the other hand, can continue to sit there watching something good without ever being interrupted. These are the only times I really wish I had a tablet, the rest of the time I'll use a real keyboard, thanks.
